Consider adding a LICENSE file

[AntonFriberg]

Hi!

I came about your project after looking for similar functionality that you have provided with this project. But I am a bit hesitant to look further into how this project solves my use case since you do not have a clear license included in the repository.

The only mentioning that I have found is in your package.json files that gives an indication that you seem to want a permissive license for this project (ISC license). If that is the case I think you would greatly benefit from including a LICENSE file in the parent folder of this repository with the license information https://choosealicense.com/licenses/.

tl:dr
If you want a ISC license for this project, include a LICENSE file with the following information:
